A Phototransistor is a two-lead or three-lead semiconductor that is more sensitive than a photodiode. It senses light levels and uses them to alter currents to create an electrical signal.The bipolar semiconductor is can be made from silicon or another semi-conductive material.How do Phototransistors work?Once detection of light such as IR (infrared), visible light or UV (Ultraviolet) is successful, the device will alter a current flowing between an emitter and collector, depending on the light and level of intensity it receives.Features and Benefits&#149;<TAB>Reflow surface-mounting support&#149;<TAB>Small, ultra-thin&#149;<TAB>High sensitivity&#149;<TAB>Electromagnetic noise resistance&#149;<TAB>High linearity&#149;<TAB>Produce a higher current than photodiodesWhere might I use a Phototransistor?A photo transistor can be used in many different devices and applications such as: &#149; Photo interrupters&#149; Industrial electronics&#149; Human detection devices&#149; TV&#149; Air conditioning&#149; Digital photo-frames&#149; PCs or Laptops&#149; Automatic switches (lighting equipment)&#149; IP cameras&#149; Security devices&#149; Home electronics
